Description

In hrev25913 and hrev26967 OpenPIC and its ppc kernel counterpart were ​hacked to compile.

So with #5193 patches we get a kernel panic: 

PANIC: arch_int_init_post_device_manager(): Found no supported PIC!

draft patch: clean up OpenPIC

comment:2 by andreasf, 14 years ago

Added a draft patch cleaning up the OpenPIC add-on:

  • add device types, IO resources and name when registering
  • clean up retrieval of PCI info in initialization
  • implement stub driver functions where NULL values were marked as "HACK"

These are my first patches touching the device manager, so patch 3 may need careful review.

via haiku.image netboot on PowerPC G3 PowerBook:

pre patches i received the following: 

syslog:
Failed to add "usb_disk": Device not accessible

kdl:
PANIC: arch_int_init_post_device_manager(): Found no supported PIC!

post patches the system locks up at pci_init (see screenshots)

Replying to kallisti5:

post patches the system locks up at pci_init (see screenshots)

What does dev pci at OF prompt say? (especially model and compatible properties)
Might be related to #6247.

Note that the patches only try to restore previous behavior. I have no idea whether that was correct or even worked at the time.

Milestone: R1

PPC should not delay R1.
